DFRobot Bluno series is an Arduino-compatible Bluetooth 4.0(BLE) hardware solution designed by makers,and for makers. All Bluno products are Bluetooth 4.0 ready,and enjoy features such as wireless programming,smart App controlling,long communication range,and plentiful periphery modules.<br><br><b>SPECIFICATION</b><br>Microcontroller?ATmega2560<br>Clock frequency: 16MHZ<br>Transmission distance: 70m in open space<br>Support bluetooth remote update the Arduino program<br>Support bluetooth HID<br>Support iBeacons<br>Support by the AT command to debug the BLE<br>Support transparent transmission serial port<br>Support the master-slave machine switch<br>Support usb update BLE chip program<br>Working voltage?+5V<br>External input voltage (recommended)?7 ~ 12V DC<br>External input voltage (range)?6 ~ 20V DC<br>Digital I/O outputs: 54 (14 PWM outputs)<br>Analog inputs: 16<br>I/O current: 40mA<br>Flash capacity: 256KB (4k for bootloader)<br>Static storage capacity of SRAM: 8KB<br>Memory capacity of EEPROM: 4KB<br>Size: 108 x 54mm(4.25 x 2.13")<br><br><b>More advantages</b><br>Compared with the first Bluetooth 4.0 integrated Arduino board , Bluno, Bluno Mega2560 not only inherits the advantages of this Bluetooth 4.0 wireless communication function, but also enables more digital and analog ports allowing bigger code storage space. That is to say, you can use Bluno Mega2560 to make more functional DIY works. Also improvement has been done on power supply, with the power input range widened to 5-23V. The board output current capacity has also been greatly increased to 2A (using DC2.1 port to supply power), which is even more fortunate.It means Bluno Mega2560 is able to connect more external sensor modules concurrently. The shield interface is compatible with the Arduino shield interface, as it was priviously. Yes, it will undoubtly become a powerful core board for making creative DIY works.
